Ponderings and fiddling with Raspberry Pi tiny computers.
Big brother to the Blinkt, small brother to the Unicorn HAT, the PHAT version is a 4 x 8 matrix of RGB LEDs.
At £10 it gives you twice as many LEDs per pound as the Blinkt (a 1 x 8 strip of the same LEDs costing £5). But what am I going to do with the extra ranks of multi-coloured shiny sparkles?...
One of my first attempts to use the PiGlow was to give some indication of the state of a headless Pi Zero as it started up and sorted out its server processes.
One of the first add-ons I bought when I started playing with Raspberry Pi Zeroes was the Pimoroni PiGlow. This is a tiny pHat (Pimoroni term for a tiny Zero add-on board) which contains 3 spiral lines of 6 different coloured LEDs.
